Thank you😀
I will load some with .327 bullets and see if it will
Work.
If this will solve the problem I leave it with that.
Otherwise I got a k98k barrel from a friend
So Maby I will turn that in Kar98a contour
An see how it will work out.

If you use boattail bullets, that alone can cause wild shots in a old rifle with a chamber designed for Spitzer bullets. The transition cone in old Mausers is often very long, so, quite apart from the correct diameter, you need a bullet with a long cylindrical section, so that (hopefully) the bullet engages the lands before the base has left the neck of the cartridge case.

Make the usual test of maximum possible seating depth. You will quite possibly have to seat the bullet as far out as it can reasonably go, i.e. leaving a minimum length equal to 1 caliber in the cartridge case.

Thank you for the adwice.
I have some bullets pulled from 8x58RD (DanishKrag)
The are .323 and flat.
I will try to load some with them along with some
With the .327 and what happens.
There will go a couple of weeks before I have
Time to try them

Hi again
Today I wass on the range with my Kar 98a.
To Patric and Jim. Both of you are spot on:-)
Patric. The flat base bullets does the job. I learned some new here. Thank you.
Jim. It was a bullet size problem the .327 boat tail worked fine as well. thank you.

picture. 5 group high flat base. 5 group left .327 boattail (sight lowered a little)
10 group first 5 flat base 5 last .327 boat tail.

I thing i went very well:-)

Distance 200m prone with no support.

Only thing now: I just got two good K98k barrels. Maybe I still want to turn one too Kar 98a
contour and use it to so I dont need "special" ammo for this rifle. HMMM
Or maby I leave it as it is. HMMM

Looks like it shoots now... I agree with standard ammo. You don't have a pure rifle anyway so if you can contour the barrel to match and looks good you already are way up on many of us that don't even have that model of rifle. There are less and less it seems...

Murphy's Law

I guess you are referring not to morphus, whoever he may be, but the famous Edward Aloysius "If anything can go wrong, it will" MURPHY. If my memory cells are still ticking over correctly, in the postwar years Murphy - yes, he really did exist - was involved in research using rocket sleds to develop ejection seats. The apparatus was, of course, well equipped with a battery of sensors to measure the stress on the seat and the test pilot. After one particularly stressful test the pilot inquired how the results had turned out.

There were none. Not just one, but every single sensor had been wired up incorrectly.
Someone is supposed to have said "Ah well, that's Murphy for you!" - and the rest is history.

Ok, there is doubtless a certain amount of "urban myth" in the story, but if you search the internet you should be able to find something about it.
